1'0 all whom it may concern.-..

I Be it known that W9,WILLIAM F. BOCKHOFF, residing at Indianapolis, county of Marion, and State of .Indiana, and EDWARD J. VON v.5 Pzrmmesiding at Dayton, in thecounty of Montgomery and State of 'Ohio, citizens of the United States, have invented certain new and useful- Improvements in Cash-Registers, of which wedeclare the following to be a full,

- clear, and exact description.

Our invention relates to'a printingattach: ment for cash-registers of the kind generally known as key-operated machines; and

' while its general purpose is to provide anovel I 'form of printing mechanism for such machines it has the added object of providing an improved key-locking mechanism whereby to lock the keys of one bank after one key in that bank hasbeen depressed and returned tonormal position until a complete operation of the machine has been effected, and although this latter device is particularly desirable as an adjunct to the printing mechanism in the special form of machine to-which we have applied our invention, yet such device may be useful in any key-operated machine. We haveshown-our improvement as particularly applied to the style of machine set 4 represents avertical cross-section taken on the line 2 2 of Fig. 1 looking in the direction of the arrow crossing said line. Fig. 2 represents a detail view of the key-arrester device. Fig. 3 represents a vertical cross-section taken on the line 3 3 of Fig. 1 looking. in direction of the arrow crossing said line. ,Fig. 4. repre- Serial No. 167,177. No modal.)

Fig. 5 represents a side elevatio'nof the left-hand end of the machine. Fig. 6 represents a detail rear elevation of part of the machine, showing the parts in their normal position.

Fig.8 represents a side elevation of the right-hand end of the machine, showing the printing attachment.

[few and laey arll'ester. Referring to Figs. 1 and 2,aseries of val ue-keys 20 are pivoted upon atransverse axis 21 andare arranged in the usual banks of units of cents, tens of cents, and dollars. These keys have formed upon their rearward extensions downwardly-extending tails 22, formed with rack-surfaces 23, which are engaged by transverse bars 24:, v whichextend across the back of the keys, one .bar for each bank and which bars are pivoted on a transverse axis at their central portions and are normally held in horizontal positions by springs 25. On the downward stroke of any key the tail 22 rises and is en gaged by the bar 24 to arrest the key and prevent retrograde movement. As soon as the key has reached its lowest position the tail 22'has been carried upward beyond the arrester-bar24. so that the bar swings back to its normal horizontal position and again engages the rack 23 on the downward movement of the tail 22. The arresterbar 24- therefore obviously acts as an arrester in both directions of movement of the operatingkeys. Resting over the endof the rear portion of each key is the stem 30 of the usual tablet indicator 31. 'Each stem is provided with a nose 32, on its rearward side, and as the stem is lifted'on the depression of any key this nose is carried upward and is engaged and held upward by the transverse bar 33 of the swinging'frame 34, which is pivot- BEST AVAlLABLE COP\ ed the mainframe at and is spring-drawn toward the indicator-stems by a spring36. At each operation .of the. machine this swinging frame34 first swung rearwardly, so as 5-- to release the previously raised indicators in the-manner to belaterdescribed.

' Registering A separate co un;

.ter-or register1 -40 is provided for eachbank of keys, and since the'register-actuating mechanisin is thesame for 'all the describe it for one bank only. Mounted loosely upon a transverse shaft' 41i, which is suitably. journa led in'the main frame, is a gear-wheel 42, the teeth of which'mesh with ,5 --*the beveled pinion 43' of the counteri40. Thisgear-wheel 42'is arranged to be moved graduated distances, according to the value of;

the depressed, thereby moving the pinion 43 graduated ,dista-nces, and suitable versely across the bank of keys and are- 3 formed with graduatedsteps, as is shown on bar in Fig. 2. The arrangement of these graduated steps i$.such that .on the depression of the keys the rear ends thereof come in contact with the rearward-stepped bar 44 35 at different points in the movement of the key,

and thereby move the. bar 44 upwardgraduated distances, and the construction and situation of 'the forward ,bar 45 is such that when the key which is operated reaches the extent of its downward movement the corresponding stepped notch of the bar 45 is moved downward into contact with the rising portion of the rear end of the key, and there by serves as a positive stop to prevent the 45 oscillating frame 43 from being overthrown.

Upon the beginning of the upward movement of the. rear end of any key said rear end comes in contact with a laterally-shifting camplate 46, mounted upon the bar 44, and by 5 shifting the same laterally forces the pawl 47 into engagement with the teeth of the gearwheel 42, 1 so that thereby as soon as the stepped-frame begins to rise its movement is transmitted, by means of said pawl 47, to the gear-wheel 42, and thereby it is evident that movement is transmitted to the gear-wheel 42 corresponding in amount to the value of the key depressed. Only a brief description of this part of the mechanism has here been given,- since it constitutes no partoE our pres'ent1n-.'

6o vention, and for a more detailed description reference may be had to the aforesaid patent. Planting mecfizm'imn. In order to transmit the correct movement of said gear-wheel 42 5 to suitable printing-wheels for printing a recbanks we shall transfer'devices are provided in the counter.

0rd of each transaction, we provide the following mechanism: The shaft 41 extends through the right-hand side'frame of the machine and has fast uponits'outer end the printer-wheel 50. (See Fig. 1.) Fasttothe 7 rear bar 44 of the oscillating frame 43 is a downwardly-extending plate 50, which has fastto its lower end a concave segment-rack 51, which meshes with the .gear-wheel-'52, mounted in a support 53,which extends upward from thebase of the machine, The gear-wheel 52 meshes withapinion 54, which in thedollar-bank ismade fast to the transverseshaft, 41, and thereby it is evident that upon an upward movement of the rear end of.

the oscillating frame 43 the gear-wheel 52 is rotated by means of the segment-rack 51, and thereby the pinion 54 and the printer-wheel 50 upon the outer end of said shaft 41 are also rotated, the construction of course being such that the printer-wheel 50 is set in this A manner to bring into printing alinementthe type-figure corresponding to the value of the key depressed. .In the units-of-tens bank the oscillating frame 43 (see Fig. 1) has attached so to it a similar segment-rack, which actuates' a pinion 54, which is made fast to a sleeve 41", surrounding the shaft 41,and which sleeve has fast upon its outer end the printer-wheel 50. Similarly in the units-of-cents bank the 9 5 'oscillatingframe 43 actuatcs the pinion 54", which is made'fast to the sleeve 41?, which sleeve carries a printing-wheel 50". It is thus apparent that in, the depression of keys in the three banks the printing-wheels are set to bring the proper type into alinementto print the amount upon the paper strip in a manner to'be described, 1

It will be obvious from the construction that-if any key in one of the banks is de- 05 pressed and immediately allowed to return to 'normal position its corresponding registering-frame and type-wheel will also be set to the proper position and will then return to their normal positions. However, itisde- I 0 sirable to provide means for allowing the concurrent use of a key in each one of the banks for any single transaction and to have the total amount represented by the depression of thesekeys in the various banks added upon :15 the counters and printed as one item upon the detail-strip. For this purpose we have provided mechanism now to be described for permitting the simultaneous or successive operation of a key in each bank and for holding the corresponding registering-frame and printer-wheels in operated positionsuntilthe printing has taken place.

Fast to the. rear of bar 44 of the oscillating frame 43 is a segmentplate'60, (see Fig. 2,)- 5 having teeth on its'rear side which are adapt d to be engaged by a pawl 61, which pawl is pivoted, as at 62, to a laterally-shifting camplate 63, the formation of which is better shown in Fig. 4, and the pawl '61 is spring- 13 BEST AVAlLABLE com pressed forward by means of a spring 64. i

The cam-plate 63 is Suspended from the main frame of the machine by means of links 65, Fig. 4, and is formed with a series of vertical slots, one for each key, and thenormal position of the cam-plate is such that the rear ends of the keys 20 lie directly-beneath the beveled lower ends .66 of the'cam-plataand on the depression of any key the rear end 20 of said key of course rises and by acting upon the beveled surface 66 shifts the cam-plate to a slight extent. laterally, and the-reanend of the key then slides upward in the slot and holds the cam-plate in its shifted position against the tension of'a spring 67. As will be seen in Fig. 1, the pawl 61 lies normally out of alinement withtherack-plate 60; but

when any key is operated the cam-plate 63-is shifted to the left, as just described, and the pawl 61 is thereby carried into engagement with the rack-plate 60, sh that when said rackplate' is carried upward by the movement of the oscillating frame 43 the pawl 61 will support the rack-plate60, and consequently sa'i'd oscillating frame 43, in its operated position,

and therefore the printing-wheel 50, come spondingto this oscillating frame 43, will also be held in its operated position. As seenin Fig. 1, there is a corresponding supportingpawl 61, a rack-plate 60 for. the units-of-tens bank, and a supporting-pawl61 and a rackplate 60 for the units-of-cents bank, whereby on the pressing of any key in these banks the respective oscillating frames: and printerwheels will be held in operated positions.

- Since the cam-plate 63 extends across all the keys in the-other banks, it is'apparent that the depression of a single key in any one bankfor example, in the dol lar-bankwill serve to carry the supporting-pawls 61, 61, and 61 into engagement with their respective rack-plates 60, '60, and to maintain these pawls in this supporting position as -long as the key remains depressed; Therefore after having depressed this key in the dollar-bank it will bepossible topress a key in any one or both of the other banks and release these other keys to their normal positions; but, nevertheless, the oscillating registerframes and printer-wheels of these other banks will.

remain supported in their operated positions 'in spite of the fact that the operated keys in these other bankshavc returned to normal positions, for the continued depression of the key in one of the banks is what serves to hold the cam-plate 63 in its shifted position, and

thereby hold the supporting-pawls in engage ment with their respeetive racks in all the banks. Thus if the operator wishes toregister a. transaction amounting to four-dollars and twenty-five cents he will tirst'depress the four-dollarkeyand holding the same depressed will then successively depress and release first the twenty-cent key and then the five-cent key, or, if desired, maydepress ward slightly ;it an angle. 'main frame at .at; its forward end by the four-dollar key is maintained in its depressed positi n, the cam-plate 63 remains shifted to the left in such manner as to hold in operated positions the oscillating registerframes and the printer-wheels of all the banks, and since the printing-wheels are now all in position to print the amountfonr dollars and twenty five cents-the printing mechanism may be operated in any manner desired, which "in this case takes place, as later described, upon the return of the four-dollar key toward its normal position, and at the end of the upward strokeof the'key the rear end of thekey is again withdrawn from the slots of the cam-plate 63 and the plate again shiftstoxthe right, so as to release the supporting-pawls 61 from engagement with their respective racks and allow the oscillating frames of the various banks, together with the corresponding printing-wheel, to return to their normal positions. The manner and sequence ofjoperation of the return of the parts to their normal positions will be described later.

In order to prevent the simultaneous operation of more than one key in any bank, the usual key-stops are provided, as shown in Fig. 6. These key-stops consist of wedge-shaped blocks 130, which are pivoted at 131 to angle arms 132, fast to the main frame of themachine, and the width of these blocks is such that when any key is depressed the blocks are crowded together in such manner that only one key can be depressed at a time, all of which is a well-known device in the art and is set forth in detail in the aforesaid Letters Patent. Since, as above described, the registeringframes become latched in their operated positions when the cam-plate 63 is held in its shifted position by the depression of any key, it is obvious that it is desirable to provide somerneans for preventing a second operation of a key in those banks other than the bank in which the key is already depressedthat is, i n the abovementioned illustration, after the four-dollar key has been depressed and held down then if the twenty-cent key in the tens-of-units bank is depressed and released to itsnormal position it is essential that it should be impossible to press another key in this tens-ofunits bank until all of the parts have returned to normal position'and the printing has taken place, and similarly with the units-bank. The device for accomplishing this is shownin Fig. 2? Formed upon each of the transverse arrester-bars 24 is a lug 135, which projects up- Pivoted to the 36 is a dog 137, formed with a nose 138, the rearward end of which dog is drawn downward by a spring 139. There is one of the se ogs for each bank of keys, and they are situated in lateral alinement with the aforesaid lugs 135. The dog 137 is engaged the rearward-stepped BEST AVAlLABLE COP:

bar 47 of theoscillating registering-frame43.

W hen the partsare'in their normal position,

the bar a7 rests upon the forward end-of the dog 137 and holds the rearward end-but of the However, assoon awith the key the dog 137 -is' of course released and its rearward end drops downward. During this part of the stroke of the key+that is,

while the arrester-rack 23 is rising-the for'-' a ward end of the transverse'arrester-bar 24 is tilted upward, as-before described; but on the.

beginning of. the return stroke of the ke'y'after the tail 22 has been freed from the transverse bar 24 the bar is then tilted in the opposite direction'and the lug 135 is forced under the nose 138," and the bar 245 is thus held in this tilted position, as shown in-dotted lines in Fig. 2, and although the key returns to its normal position, yet if the registering-frame is still held displaced from normal position the i nose 138'willstill engage the lug-135 and the bar 24:v remain latched in'this position, whereby it is obvious that if the'sa'me key or. any other key in this same bank is attempted. to

be depressed such key will be locked from operation by contact with its arrester-rack 23 with the bar The bar obviously remains in thislatched position until the registeringframe 43 has descended to itsnormal position,

when the forward end of the dog 137 is again depressed and the rearward end lifted, thereby allowing the bar'24 to return to its normal ,horizpntal position,the return of the parts to their normal positions taking place, as beforestated, as soon as the last key has returned to its normal position and has allowed the camplate'68 to shift, and thereby'allow the registeringframes to drop. It is apparent from this construction that it is impossible after having once pressed a key inany bank and set the registering-frames and printing=wheels in their operated positions to press another key ,in this same bank until the printing has taken a place. 7

The operation of the printing mechanism for recording the amount of each transaction upon the detail-strip is as follows: Extending transversely across all the-keys slightly in the rear of their pivotal points is a'universal bar 70, (see Figs. 1 and 3,) which bar is.swung upon side arms 71-, pivoted on the shaft 21, upon which'tbe keys are-pivoted, and obviousl y the bar 70 receives a uniform movement at each operation of the machine, being carried upward by contact with the upper sideofthe rear end of the To the righthand end of the universal bar 70 is attached a plate 72, (see Fig. 3,) which is formed witha slot 7 3,. which engages a pinf74 on the for-v ward end ofa'lever 75, pivotedat 76 tothe side frame 77 of the printing attachment. 'At the rearward end of. the lever 75 is pivoted, as at ,7 7", a pawl 78,- formed at its upper end with a nose 79. which nose engages a lug 80, formed on-the side of the printer-hammer 81, which printeri-hammer-is pivoted, as at 82, on the outer. side of the side frame 77 and carri'esa resilientplaten 83, adapted to engage the type-wheels 50, and 50 Sincethe printer-hammer 81 is on the outer-side of the side frame 77 and the pawl 7 8 is on the inner side thereof, 'the side frame 77 is vprbvided with a recess 84:,through which the said lug "80 projects to be engagedeby thenose79 of the pawl 78, and the pawl 78 is held in engagement with this lug 80 by means of a spring 85. The printer-hammer 81 is norinally held in its upper position by means of a spring-pressed plunger '86, (see also Figf 8,) which plunger engages alug 86*, 'formed'upon the printer-hammer 81. Pivoted at 87 to the side frame 77 is a swinging arm 88, which is normally held, by means'of a spring 89, in engagement with a stop-pin 90, extending outward from the side frame 7 7. The lower end of this arm 88 is formedwith a beveled lug 91, which is adapted to engage a similar beveled lug 92, formed uponthe rear side'of the pawl. 7 8. The operation of these'parts is as follows: When any key is depressed, the bar is'carried upward, and thereby by means of the slot-and-pin connections 73 and 7e swings the lever about its pivot 76, carrying the rear end thereof downward, and since the nose 79 of the pawl78 is in engagement with the lug onthe printer-hammer 81 the printer-hammer is thereby also carried downward against j'the pressure of the' springpressed plunger 86, and the beveled lug-92 slides over the forward'side of the beveled lug 91 and forces the lower end of the arm 88 .rearward against the tension ofthe spring 89, and .the pawl 78 is unaffected thereby. However, as soon as the universal bar 7 0 begins to descend the rearward end of the lever 75 begins to ascend, and the upper surface ofthe beveled lug 92 engages with the under surface of'the beveled lug 91, and since the arm 88 cannot swing forward because of the stoppin the pawl 78 is thereby forced outof engagement with the lug 80, and consequently the printer-hammer is released and flies upward, carrying the platen 83 against the typewheels. 7

e The type-wheels are provided with the usual alinin'gpawls 93, which are pivoted, as at 94:

in the frame 95,to=the side frame 77 on a stub-shaft 96. Each type-wheel is provided with an alining star-wheel 97, fastupon the side of the type-wheehwhich star-wheel Ts engaged by its respective alining-pawl, and the 95, which springs force the rear; end of the -alining-'pawls up against a transverse bar 99 onthe frame 95. The frame is made fast 'alining-pawls are made individually flexible j by means of springs 98, mounted in the-frame at its pivotal point to a downwardly-extending arm 100, which arm has formed upon its lower end a beveled lug 101, adapted to be en gaged by a similar beveled lug 102, formed specti've star-wheels, and upon the downward movement of the universal bar and the consequent upward movement of the rear end of. the lever the lug 102 slides upon the forward side pf the lug 101 and forces the arm 100 slightly rearward, so as to jam the aliningpawl s 93 intofirm engagement with their respective type-wheels to hold the latter firmly in position while the printing is taking place,

which, as previously described, occurs upon the initial upward movement of this rear end of the lever 75." As soonas the lug 102 has moved past the lug 101 the arm 100 is free to move forward, and thetype wheels-can then.

return to their normal positions, since the alining-pawls no longer positively hold them .in their operated positions. The alining-pawl frame95 is normally drawn downward by a spring 103, whereby the armis normally held in its rearward position.

The position and the operation of the detail v strip'can best be seen in Fig, '.The paper is unwound from-a supply-roll. and is led -up over guide-rollers 10.6, with a stretch of the paperextending between the type-wheels and the platen 83, and the paper is then led down around a winding-roller 107. The paper re-.

ceives a spacing'm'ovement at each operation of the machine by means ofa pawl 108, which vroller 107.

engages a ratchet 109, fast upon the winding- "This feed-pawl is pivoted at 109 t'oan arm 110, which is mounted upon a stubshaft 1 1 1, jou rnaled in theside frame 7 7. This stub-shaft 111' extends through to the inner side of the'side frame 77, where it has fast upon it an-a-rm 112, carrying a pin 113, which plays in the slot 114, formed'in the lever'75. Upon the rocking of-the lever 75in the man-. ner before described it is apparent that the arm 112, and consequently the arm 110, will berocked upon the shaft 111 in such manner that the feed-pawl 108 will be first thrown rearward to spacethe strip and will then be returned'to its normal position without any further feeding movement.

, Upon the winding-roller 107 is a gear-wheel- 120, which meshes with an intermediate pinion 121, mounted on a shaft journaled-in the side frame 77,". which pinion in turn meshes BEST AVAlLABLE COP:

upon astub-shaft journaled in the side frame 77 andwhich also carries an outwmdly-extending roller, around which is passed the.

inking-ribbon 123, which inking-ribbon passes betweeuthe type-wheel's and the detail-strip, then around a guide-pin 124, over a roller 125, .mounted loosely upon the shaft 96, and over a supporting-roller 126. It is thus obvious that by meansv of these gears 120, 121, and V 122 the inking-ribbon 123 also receives a spacing movement by means of the pawl 108 at each operation of the machine.

The mechanism which producesthe sequence of operation of the various parts to effect the printing and return these parts to their-'normal positions will now -be described.

Fastto the left-hand end of the universal bar 70 is a rearwardly-eXtending lever, 140,

similar in shape to the rear ends of the keylevers. (See Fig. 5.) At the rearward end of this lever is pivoted a pawl 141,-the upper end of. which is drawn rearward by a spring 142, attached to the lower. end of said pawl-- The upper end of this pawl is formed with an inclined head 143, below which is fastened an antifriction-rbller 144; The rearwardmovement of the upper end of this pawl is limited by a stop-pin 145, which is adapted'to abutagainst the lever 140., Thepawl141 is loosely pivoted upon the lever in such manner as to allow a slight lateral movement against the A pressure of a spring 146, which extends up-' ward from the lever 140. Extending outwardly from the left-hand end'of. the shifting cam-plate 63 (see Fig. 7) is an arm 147, which is adapted to be engaged by the pawl 141; Pivoted to the main frame at is a pawl 151, formed with a nose which engages a pin IOO 152, fast upon the shifting cam-plate 63 and.

extending rearwardly through a slot 153, formed in the main frame. The pawl 151 is normally drawn downward by means of a spring 154. Also pivoted at 150 is a trip-lever 155, which has at its right-hand enda pin 156, which engages the pawl 151, and this pin is drawn upward by means of a spring 157; but the spring 154 beingstronger than the spring 157 the normal positions of the pawl and lever is as shown-in 'Fig. 6. Upon the operationof any keythe cam-plate- 63 is shifted laterally to the'left, as before explained, whereupon the pin 152 immediately passes by the nose of the pawl 151 and thepawl resumes its normal. position ready to engage the pin on its return shifting movement, the camplate 63' being held in its shifted position, not by means of this pawl, but by the engagement ofthe key-lever'with the slot in the cam-plate, as heretofore stated. At the same time, the raising'of the universal'bar 70 carri'es with it the lever 140, and the pawl 141 (see Fig. 5)'is thereby'elevated, and its beveled head 143 slides bythe laterally-projecting" with another gear 122, which is also mounted arm 147 of the cam-plate'63, and at the limit of the upward movement of this lever 140 the BEST AVAILABLE copy pawl 141 locks over this arm147, with the antifriction-roller 144 resting upon the arm, whereby the lever 140, and therefore the universal bar 70, is held in its raised position. This position is shown in Fig. 7. The rearward end of the lever 140 engages the lefthand end of the trip-lever 155 (see 6) I during this upward movement, but simply snaps by this lever without affecting the pawl 151. All this operation of the parts takes place while any key is being depressed, and it is upon the return of the key to its normal it having been previously stated that the op-..

, eration of the printing-hammer takes place upon the beginning of'the downward movement of the universal bar 70. This shifting of the cam-plate 63 to the right takes place when the key has returned almost to its normal position-that is, when the rear end of the key-lever has again come opposite the beveled surface 66 of the shifting cam-plate. As soon as the key has reached this position the cam-plate of course begins to shift laterally to the right; but it has only a partial initial movement, for it is caught and held in partially-shifted position by the engagement of the pin 152 with the pawl 151. However, this partial movement is suflicient to bring the end of the arm 147 slightly beyond the center of the roller 144 of the pawl 141, so that the lateral movement of said pawl will allow it to free itself from the arm 147 and crowd by the end thereof, whereby-thelever 140 and the universal bar, are allowed to drop, and on the beginning of this'dropping movement the printing-platen is operated to take the impression from the type-wheels. Although the key may have fully returned to its home position and be free from the inclined ends 66 of the cam-plate 63, yet the cam-plate does not return immediately to its normal position; but, as explained above, it is caught by engagement of its pin, 152 with the nose of the pawl 151,'and thereby held in its partially-shifted position until the rear end of the lever strikes the left end of the trip-lever 155, and thereby raises the pawl 151 by means of the pin 156, so as to free the pawl from the pin 152 and allow the camplate to return completely to its normal position. By this means the printing-wheels are held in their set posi ions until the printing has taken place, and the-cam-plate cannot be released to its normal position, so as to un-' latch the oscillating frame and their connecttype-wheels, until the pawl 151 has been operated by the downward movement of the lever 140, which operation takes place after the universal bar 0 has descended far enough to operate the printing-hammer. Since this entire operation of the release of the parts takes place almost at thelimit of the upward movement of the key-'that is, when the end of the key-lever again reaches the beveledsurfaceof' the cam-plate it is obvious that this sequence of operation of theparts is practically simultaneous and that it is impossible to operate the machine so rapidly as to prevent the'prop'er sequence of operation.

Flash mechanism. In order to operate the flash which -conceals the indicators until-the complete operation of the machine, we provide the following mechanism: The flash (see Fig. 5) is mounted upon suitable rods 161, which slide in guideways in the main frame, and one of these rods extends downthe lever 140. Pivoted at 162 to the main frame is a lever 163, formed at its lower end with a hook 164, Fig. 6, having a beveled surface 165, whichis adapted to be engaged by the lever 140 and formed at its upper end with a lug 166. Upon the upward movement of the lever 140 the rear end thereof engages the rod 161 and elevates the rod and its flash until the shoulder 167, formed on the lower end of the rod -,'161 is opposite the lug 166, and in this position the weight of the lower end of the lever 163 is such as to throw the lug 166 into engagement with the shoulder 167 and hold the flash in'its upward position,

and upon the return of the lever 140 to its 5 ward in alinement with the rearward end of normal lower position the rear end'of the le-' 'ver engages the beveled surface 165 and forces that end of the lever 164 inward", and thereby carries the lug 166 out of engagement with the shoulder 167 and allows the flash to drop and display the indicators. 7

Release f0rndicat0rs.The releasing of the indicators which have been exposed on the previous transaction is accomplished by means of an arm 170, (see Fig. 5,) which is fast at its upper end'to the shaft 35, which carries projecting pins 180,that contact with laterallyextending pins 181 on the swinging frames 34. (See Fig. 2.) The lower end of this arm 170 is beveled, as at 171, and is engaged by a lug 172 upon the lever 140. From this construction it is apparent that upon the upward movement of the lever 140 the lug 17 2 engages the beveled surface 171 and rocks the arm 170 rearward, thereby carrying all of' the swinging frames 34 rearward and out of engagement with the noses 32 upon the indicators'tems, thus allowing the previously-exposed indicators to drop, and upon the downward movement of the lever 140 the lug 172 slides over the rearward part of the beveled surface 171 and forces the arm 170 forward Without aflecting the frames 34.
